PCB-Keychain
About the PCB-Keychain
PCB-Keychain is an open source PCB design by RichardM-1337, published on GitHub under the MIT license. It is a 2-layer board measuring 42.2 × 34.1 mm, with 5 components from 5 distinct parts.
Other key parts include the 13.56MHZ. By type, the board carries 1 IC, 1 diode, 1 inductor, 1 capacitor and 1 resistor.
From the project
A cool keychain that will also act as a nfc of sorts that I can bring around wherever I go.
A simple yet kind of complex project that I will be undertaking in order to enhance my own pcb knowledge and be more experienced with using KiCAD.
